A placekicker must kick a football from a point 36.0 m (about 40 yards) from the goal. Half the crowd hopes the ball will clear the crossbar, which is 3.05 m high. When kicked, the ball leaves the ground with a speed of 21.0 m/s at an angle of 46.0° to the horizontal. (a) By how much does the ball clear or fall short of clearing the crossbar? (Enter a negative answer if it falls short.)  _______m (b) Does the ball approach the crossbar while still rising or while falling? rising or falling?

How do you solve this? I've got 2/3 so far

On a beautiful spring day, Juan is playing a round of golf. He hits the golfball with an initial velocity of 37 m/s at an angle of 27.4°. If it hits the ground 5.8s later, how far does it travel? Ignore air resistance. Answer: m

1. A player lines up to kick a 40 m goal. In the first attempt, the ball has an initial velocity of 20 m/s at angle of 55.0 degrees. The goal posts are 3 m high. Ônce the ball passes above the field goal post (i.e., after it has travelled 40 m in the horizontal direction), it is deemed successful. (a) Determine if the goal kicker's first attempt is successful. (b) If the kicker changes the angle of kicking to 30 degrees and the initial velocity so that it JUST reaches the goal post. Determine the new initial velocity of ball.

CANNOT BE HAND-DRAWN, THE EXPLANATION MUST BE TYPED OUT
